Description
Technical field
The utility model relates to a kind of rectifier transformer low-voltage copper bar fixed structure, belongs to transformer copper bar fixed network.
Background technology
Transformer low voltage copper bar is connected to the in-out end of low-voltage coil, mostly current low-voltage copper bar is owing to being to adopt the larger monolithic copper coin of thickness to make, and be laterally three transformer low voltage copper bars are clamped simultaneously with fixing by primary cable folder in assembling process, when transformer runs, the electromagnetic force produced due to big current easily causes transformer low voltage copper bar to produce mutual active force, simultaneously also because transformer low voltage copper bar adopts primary cable folder laterally to accommodate simultaneously, very easily produce the distortion of transformer low voltage copper bar and cause lead wire insulation distance to change, and then very easily cause transformer operation to occur catastrophe failure.
Summary of the invention
The purpose of this utility model is: provide a kind of structure simple, clamping force firm stable, and insulation is reliable, can effectively avoid transformer low voltage copper bar to be out of shape cause transformer fault to occur rectifier transformer low-voltage copper bar fixed structure.
The technical solution of the utility model is:
A kind of rectifier transformer low-voltage copper bar fixed structure, comprise low-voltage copper bar, insulation board and the channel-section steel for stationary transformer iron core, it is characterized in that: be welded to each other by low-voltage copper bar between the in-out end of low-voltage coil, on the channel-section steel of low-voltage copper bar side, symmetry shape has been welded fixed head, and fixed head is provided with fixing hole; The superposition of low-voltage copper bar upper strata is held shape and is provided with multiple insulation board, and insulation board is fixedly mounted on fixed head by fixing hole by set bolt.
The beneficial effects of the utility model are:
This rectifier transformer low-voltage copper bar fixed structure structure is simple, practicality is good, in the course of work, low-voltage copper bar is fixed on channel-section steel by insulation board by set bolt and fixed head, the distortion that can effectively prevent low-voltage copper bar from producing under the effect of electromagnetic force, makes transformer run more secure, reliable.Solve existing transformer low voltage copper bar adopts primary cable folder laterally to accommodate simultaneously, very easily produces the distortion of transformer low voltage copper bar and causes lead wire insulation distance to change, and then very easily causing transformer to run the problem occurring catastrophe failure.It is large that this rectifier transformer low-voltage copper bar fixed structure has clamping force, and insulate more reliable feature, is specially adapted to the fixing use of rectifier transformer low-voltage copper bar.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In figure: 1, low-voltage copper bar, 2, insulation board, 3, channel-section steel, 4, fixed head, 5, set bolt.
Embodiment
This rectifier transformer low-voltage copper bar fixed structure comprises low-voltage copper bar 1, insulation board 2 and the channel-section steel 3 for stationary transformer iron core.Be welded to each other by low-voltage copper bar 1 between the in-out end of low-voltage coil, on the channel-section steel 3 of low-voltage copper bar 1 side, symmetry shape has been welded fixed head 4, and fixed head 4 is provided with fixing hole.The superposition of low-voltage copper bar 1 upper strata is held shape and is provided with multiple insulation board 2, and insulation board 2 is fixedly mounted on fixed head 4 by fixing hole by set bolt 5.
This rectifier transformer low-voltage copper bar fixed structure is in the transformer course of work, low-voltage copper bar 1 is fixed on channel-section steel 3 by insulation board 2 by set bolt 6 and fixed head 4, the distortion that can effectively prevent low-voltage copper bar 1 from producing under the effect of electromagnetic force, makes transformer run more secure, reliable.Solve existing transformer copper mining primary cable folder thus laterally to accommodate simultaneously, very easily produce the distortion of transformer copper bar and cause lead wire insulation distance to change, and then causing transformer to run the problem occurring catastrophe failure.This rectifier transformer low-voltage copper bar fixed structure has that structure is simple, practicality good, and clamping force is large, the more reliable feature of insulation, is specially adapted to that rectifier transformer low-voltage copper bar is fixing to be used.
